编辑：对不起，我的错误：我'未正确申报:)现在应该没事使用

I want to exit a while() when the user enters a negative number of any size. What kind of condition would I need at the start of the loop to get the loop to exit when the user enters a negative number?

解决方案

int i = -1;
do
{
    i = magic_user_input();
    //simple enough? get a decent programming book to get the hang of loops
}
while(i > -1)

edit: sorry, my mistake: 'i' wasn't declared properly :) now it should be fine to use
